To all whom il may ama-n:

Be it known that 1, WILLIAM BriAoxMoaE, a citizen of the. United States, lresiding at, Cleveland, Cuyahoga countyyhimhave inl vented a new and useful Improvement in Coupling-Pockets for. Radial-Draft Gears,

-of which the following is a specification, reference being had to the accompanying drawi'n s, in whichv, `ig`ure 1 is a planpartly in section of my improved construction; Fig. 2 is an eleva vtion partly in section thereofyFig. 3 is a section on lines IIL-IH of Fig. 2 and Fig. 4 is a section on Vlines IV-IV of Fig.42; and Il' Fig. is an elevation partly in section showing my improvements as used with a Master Car Builders couplert My invention relates to radial draft gears and providesment of the coupler shank to the draft mem lier or coupler lshank extension. It is applicable alike to couplers havingr specially constructed shanks andto those of the Master Car Builders type.

Referring to the drawings, 2l indicates the I coupler shank extension or draft member, the'forward' end of which terminates in a pocket portion 3, adapted to receive. the Shanks of different styles bf couplers. The 0 numeral 4 indicates an automatic coupler of any suitable type, having a shank 5 specially constructed for insertion into the. pocket portion 3. The shank 5 has the usual liner block portion 6 with vertically-extending g5 rivet holes 7, and. the usual transverse slot 8 'ust forward of the liner block. Upon the otto'm and top of the coupler shank are integral ribs 9 adjacent to the head of the cou 4pler.l These-ribs 9 are adapted to center the shank ofA the coupler vertically within the pocket of the shank extension. s ince the mouth of the pocket plast necessarlly be of snllicient vertical depth to receive the liner block 6, which is normally deeper than the shank 5. The coupler shank is inserted into the pocket and pushed rearwardly until the forward edge of the pocket abats against `the head of the coupler and forms a bulling surface therewith.' The key .l0 .is then inl the apertures 11 and pocket pt lion of the'coupler shank extension, whichrcgister with the slot 8 1n' the coupler shank. Bearing blocks 12are 1nserted inunediately above andv below the coufront ofthe forward plpler shank, just in an improved form of attachf longer than the width of the pocket edges of the liner block and register in Aslots 13 formed in the'side'wells of the I The key 10, after insertion', is held 1n position by the bolt 14,"which yis passed through one of the usual rivet holes 7 of the coupler shank 5 and bears in a notch on the rear side of the ke lateral removal. nderneath the head and then'ut.l respectively of thebolt 14, and on the exteriory of the pocket 3, are securing rnembers 15, which have formed integral with their"` forward ends inwardly-extending dowels 16', which pass through 'openings in the upper and lower walls of the pocket and into registering apertures in the bearingblocks 12.

When the bolt 14 is placed in position with the securing members thereon, and the nut is screwed home, thefholt, the keyglO and the bearing blocks 1Q are firm] held in4 position. l This avoids having the blocks project outwardly from the sides of the shank extension for the purpose of receiving additional fastening means, and enahlesthem to he cut olf flushl with the'sides of the pocket portion of the shank extension.

I have shown in Fig. 5 my device as a plied to the shank of an ordinary M. C. coupler. With a coupler 0f this character theattachments at the rear end are `made in precisely the same way as I have described with regard tothe construction shown in Figs. 1, 0, 3 and A4f. The MfG. B. coupler,` however, has, no vertically centering ribs, and in order to properly center the coupler shank in the coupler pocket at its forward end loose lill pieces 9',- tute for t; ie integral ribs 9 shown in Figs. 2 and 4.

Various modilications may be made in the constructions which I have shown anddescribed hcrein, without departing from 'my pocket.

, invention. What I claimis:

1.v A draft gear having a pocket for rece I tion of the liner block of a coupler shan slots in the walls of the pocket for the rece-I tion of bearing blocks,I the said bearing blocks in their greatest dimension not being and being adapted to engage'the forward edges of the liner block, and means coperating with lthe pocket; for preventing lateral movement of the bearing blocks.

2. A draft gear having a forwardly i exeys and bearing- 10, and so prevents' its are provided as asubstitending pocket adapted to receive a coupler,y

a coup er having its shank rigidly secured therein, v'the head of said coupler having a, shouldered engagement with the forward edges of said pocket, the inside vertical depth of said pocket being greater than theJ depth of the coupler shan k, and ribs between the horizontal faces of thevcoupler shank and upper andA lower walls of said pocket `ada ted to hold the coupler in a substantialy horizontal position.

3. A draft gear having a. pocket for reception ofl a coupler shank, a plurality of keys engaging Athe coupler shank and the pocket for securing the coupler shank in the pocket, a vertically-extending bolt and securing members attached thereto, said bolt and securing members being adapted to hold Ythe keys against horizontal movement.

4. A draft gear having an integral forwardly extending pocket having .horizontaltop and bottom walls adapted to receive differently dimensioned shanks of car couplers, a coupler. adapted to be inserted into said pocket from the forward side, means removable with the coupler between said shank and the walls of said pocket, adapted to hold said coupler in substantially horizontal position within the pocket, and means for tixedly securing the coupler in said pocket.

5. 'A` draft gear having a.: forwardly extending pocket adapted to receive a coupler, a coupler having its shank secured therein,

the head of said coupler having a shouldered engagement with the forward edges of saidpocket, the inside vertical depth of said poeket being greater' 'than the depth of the coupler shank, and ribs on said shank ad jacent to the' head adapted to engage the upper and lower walls of said pocket to hold the coupler in substantially horizontal posi-v tion. .v I

6. A draft gear having a pocket for the reception of the liner block of a coupler shank, and having a bufiing bearingagain'st the coupler forward of the liner hloekrslots 1 in thie walls of the pocket for` reception of bearing blocks, the said hearing blocksbeing adapted to engage the forward edges 'of the liner block, a horizontal key men'iber insertible through the walls of' the pocket and tl'lrough the coupler shank, and means in the. central vertical plane of the pocket and coupler shank for [nevent-ing lateral movement of the hearing blocks and the key member.
